IQS266-0-QNR Integrated Circuits (ICs)

IQS266-0-QNR is a touch-sensing device which is a self-capacitance type capacitive sensing solution, enabling user-interfaces to detect the presence and location of objects on the surface of the device. It is designed to provide a low power solution with optimal power savings along with a high resolving accuracy. IQS266-0-QNR consists of an array of self-capacitance sensing elements, making it ideal for standalone applications, or for higher level systems such as point-and-click gui applications.

The IQS266-0-QNR capacitive touch sensing system includes a transceiver, touch finger model (TFM), and receiver unit. The transceiver unit is the main sensing element, scanning the touch area of the device to detect touch events. The transceiver is also responsible for generating reference capacitance values during the scanning process. The TFM unit contains a small array of self-capacitance (or “finger”) cells that are used to detect the presence of a finger, and then locate its exact coordinates. The receiver unit is responsible for receiving signals from the touch area, and then relaying them to a controller unit for further processing.

IQS266-0-QNR is a highly accurate capacitive touch sensing system due to its unique sensing technology. It features a proof-integrated multi-sensing element to accurately measure the presence, size and position of an object on its surface. IQS266-0-QNR’s low-power consumption and its small package size make it suitable for many embedded applications that require accurate and sensitive touch sensing. Furthermore, the IQS266-0-QNR offers powerful algorithms to eliminate interference and noise, resulting in extremely accurate touch sensing.

The working principle behind the IQS266-0-QNR capacitive touch sensing system is based on a capacitive sensing structure. This sensing structure consists of a transceiver unit, TFMs and a receiver unit. The transceiver unit uses a 2D array of self-capacitance cells to sense the presence, size and position of an object on the surface of the device. When a finger or other conductive object approaches the sensing area of the device, a change in capacitance is detected that is relayed to the TFM. The TFMs then send a signal to the receiver unit which further processes the signal and runs a threshold detection algorithm to distinguish between valid touches and false positives. The receiver unit then passes all relevant data to the controller for further processing and integration to the device’s logic.

The IQS266-0-QNR capacitive touch sensing system is an essential tool for embedded applications that require an accurate and sensitive touch sensing solution. It is suitable for a wide range of applications, including gaming, medical, industrial and consumer applications. IQS266-0-QNR’s low-power consumption and small package size make it ideal for compact devices, while its high accuracy and interference rejection ensure reliable operation even in the most extreme conditions.
